Modifiable health behaviors and short-term medical costs among health plan members.

PURPOSE: Describe the relationship among modifiable health behaviors and short-term medical costs. DESIGN: Prospective study linking cross-sectional survey data that assessed modifiable risk behaviors with insurance claims. SETTING: A large health plan in Minnesota. SUBJECTS: A stratified, random sample of 10,000 yielded an analytic data set for 7983 members. MEASURES: The dependent variable was per-member-per-month insurance payment plus subscriber liability. Eighteen months of medical costs were analyzed. Control variables included subscriber age, sex, type of insurance plan, days of enrollment, chronic disease status, education, and marital status. Independent variables, included self-reported health behaviors of smoking, heavy drinking, nutrition, and physical activity. ANALYSIS: Linear regression was performed on the natural log of the cost variable, followed by a retransformation to dollars. RESULTS: Physical inactivity and smoking were significant predictors of higher medical costs. Each day a member did not exercise there was a 2.9% difference in cost. Compared with never smokers, current smokers had 16% higher costs. Former smokers who had quit more than 1 year before taking the survey had 15% higher costs than never smokers. Recent former smokers cost 32% more than never smokers and more frequently experienced smoking-related medical conditions before they quit. Alcohol consumption was nonsignificant. Nutrition also was not significant but was narrowly measured by only fruit and vegetable consumption. CONCLUSION: Physical inactivity and smoking were associated with higher short-term medical costs among health plan members.

The impact of smoking-cessation intervention by multiple health professionals.

BACKGROUND: Smokers have contact with many different types of health professionals. The impact of tobacco intervention by multiple types of heath professionals is not known. METHODS AND MATERIALS: As part of the 2003 Minnesota Adult Tobacco Survey, smokers (n=1723) reported on tobacco treatment by medical doctors, nurses, dentists, pharmacists, or other health professionals. This analysis examined: (1) smokers' report of tobacco intervention by different types of healthcare providers, (2) the proportion of smokers who report intervention by multiple provider types, and (3) the relationship between smokers' report of intervention by multiple provider types and readiness to quit, quit attempts, and recent quitting. RESULTS: Among past-year smokers, 65% had visits with two or more types of health professionals. Among smokers who visited health professionals (n=1523), only 34% reported being asked about smoking by two or more types of professionals. Among current smokers (n=1324), advice or assistance from more than one type of professional was uncommon (26% and 7%, respectively). Being asked about smoking by two or more types of professionals substantially increased the odds of recent quitting (OR=2.37; 95% CI=1.15-4.88). Among current smokers, being advised to quit by two or more types of professionals increased the odds of having made a quit attempt in the past year (OR=2.92; 95% CI=1.56-5.45) or intending to quit in the next 6 months (OR=2.17; 95% CI=1.10-4.29). CONCLUSIONS: Smoking-cessation interventions by more than one type of health professional have the potential to substantially increase quitting and readiness to quit in the population.

The validity of epilepsy or seizure documentation in nursing homes.

Recent studies have reported that epilepsy and seizures are common in nursing homes. Prevalence has been reported to range from 5 to 9% and antiepileptic drug (AED) use is even more common. Most of these studies have relied on various forms of nursing home records, but the validity of this source data, while assumed, has not been verified. This study evaluated the degree of agreement between the Minimum Data Set (MDS), both paper and electronic versions, and actual medical records available at the nursing home. Records of 144 residents were evaluated; agreement between paper and electronic versions of the MDS was 97.8%. Agreement between the paper version of the MDS and neurologists review of the nursing home record was 92.3%. However, the criteria for diagnosing epilepsy or seizure were not well documented. Nevertheless, the agreement among nursing home records, paper MDS and electronic MDS is great enough to allow the electronic MDS to be used as a research tool, but more investigation of the actual criteria used by nursing home physicians in diagnosing epilepsy and seizures is necessary.

Treatment of tobacco use as a chronic medical condition: primary care physicians' self-reported practice patterns.

BACKGROUND: The goal of this study is to better understand factors related to physician treatment of tobacco as a chronic medical condition. METHODS: In the fall of 2000, we conducted a mail survey of primary care physicians in a large mid-western health plan. The response rate was 61% (750/1235). The survey assessed physician attitude, perceived clinic support, training, and self-reported tobacco treatment practices. RESULTS: Twenty-nine percent of physicians reported incomplete or minimal care. Thirty-nine percent reported providing assistance without follow-up, while 21% reported providing follow-up to tobacco users making quit attempts. Only 12% of physicians reported assistance and follow-up for all tobacco users. Controlling for differences in physician and clinic characteristics, more positive physician attitudes decreased incomplete or minimal care (OR = 4.62 most positive tertile vs. least positive, P < 0.001) but did not increase follow-up activities. Higher perceived clinic support increased follow-up care (OR = 2.69, highest tertile vs. lowest, P < 0.001). Physician training was associated with increased provision of ongoing care (OR = 1.88 per additional hour of training, P < 0.001). CONCLUSIONS: Physician attitudes, clinic support, and training are related to different steps in the adoption of more complete tobacco use treatment. These findings support the need for multifaceted approaches to improve tobacco treatment as a chronic medical condition.

Antiepileptic drug use in nursing home admissions.

Although 1 of 10 nursing home residents is taking an antiepileptic drug (AED), no study to our knowledge has determined whether most residents are already receiving AED treatment when they are admitted or are given these drugs afterward. That differentiation was the focus of this study. The study group consisted of 10,318 residents, 65 years and older, admitted to 510 nursing homes located throughout the United States during the first quarter of 1999. AED prevalence at admission was 7.7%; three fifths had an epilepsy/seizure indication. In a multivariate analysis, factors associated with AED use at admission included epilepsy/seizure, bipolar depression, age group, and cognitive performance. In the follow-up cohort (N = 9,516), postadmission initiation of AEDs was 2.7%; one fifth had an epilepsy/seizure indication. In the multivariate analysis, factors associated with postadmission AED initiation included epilepsy/seizure indication, bipolar depression, age group, peripheral vascular disease, and cognitive performance. This rate of AED postadmission initiation within the first 3 months of admission was much higher than expected, suggesting that new symptoms may develop after admission. Results also show that the rate of AED use in nursing homes is not static.
